The article emphasizes the importance of evaluating data quality and addressing errors before proceeding with analysis in IoT applications, particularly in the context of Ambient Assisted Living (AAL) systems. It defines two main types of errors that can occur in IoT-sourced event logs: missing events (incomplete data) and noises (erroneous events).
The authors use a dataset collected from a smart home case study to investigate the impact of errors and evaluate the effectiveness of error correction techniques. They first analyze the dataset to identify the prevalent error types and problematic sensors/events. Then, they employ a rule-based approach tailored to the case study to address the identified errors.
The rule-based error correction method focuses on detecting and correcting noises by defining rules based on the expected behavior of the IoT system and the characteristics of the collected data. The authors compare the performance of the rule-based approach with a preliminary process mining-based error correction technique.
The results show that the rule-based method is more effective in managing noises, as it leverages the experts' understanding of typical behaviors to reduce the likelihood of inaccurate corrections. The article concludes that by identifying the main reasons for capturing errors during data collection, the error correction methods can be adapted to address the errors more effectively.
